Avaliação Higiénico-Sanitário e qualidade microbiológica do pescado Sardinha (Thryssa vitrirostris), Corvina (Johnius dussumieri) e Taimha (Mugil cephalus ) comercializado no Mercado Torrone ao ar Livre, Distrito de Quelimane, Província da Zambézia

Abstract

The selling of fish and hygienic - sanitary quality in public markets are components that should be taken into consideration on a daily basis, in order to avoid compromising public health. The objective of this study was to verify the hygienic-sanitary conditions of three species of fish, namely (Thryssa vitrirostris, Johnius dussumieri and Mugil cephalus), as well as the microbiology and sensory quality of the Torrone market, Quelimane City, where the fish is sold. An observational study and semi - structured interviews were done involving 32 sellers of the fish of the market under study. Seven fish samples were obtained and 5 samples of the Tainan were submitted for microbiological analysis. One Sample of corvine and one sample of Sardinia. That was evaluated at the sensorial level. The microbiological analyzes obeyed the following parameters (Quantification of Aerobic Microorganisms at 300C, Total Quantification Coliforms, Confirmation Term tolerant, Echerichiae coli, Salmonella ssp, Staphylococcus, positive enumeration, Vibrio cholerae, Vibrio parahaemolyticus), following the protocol used in the Fish Inspection National Institute Laboratory in Quelimane. Considering the results obtained, during the research it was noticed a lack of adequate conditions for the trade of the fish in the studied place as well as the manipulators. The values obtained in the sensorial analyzes 84.5% of sardinia was in poor physical condition and unfit for consumption and corvine analyzed 77.5% was in good condition in physical defects. With regard to microbiological of Tainan analyzes for aerobics 300C was 6.6x10^4(UFC/g), total coliforms 14.2(NMP/g), Thermo tolerant Coliforms <3(NMP/g), Escherichiacoli <5.2(NMP/g, Staphylococcus, positive n0ufc/g quantity <10^2 (UFC/g). The fish did not present microorganism such as Salmonella spp, Vibrio cholerae and Detention and enumeration of Vibrio Parahaemolicus. It can be concluded that although the hygienic-sanitary conditions of the sellers and the place of sale of the fish are unsatisfactory. The results of sensorial and microbiological parameters of Thryssa vitrirostris, Johnius dussumieri and Mugil cephalus sold Torrone market, Quelimane They were within the standards established by the Mozambican Fishery Products Inspection and Guarantee Regulation
